VkImageViewUsageCreateInfo

The set of usages for the created image view can be restricted compared to the parent image’s usage flags by adding a VkImageViewUsageCreateInfo structure to the pNext chain of VkImageViewCreateInfo.

The VkImageViewUsageCreateInfo structure is defined as:

typedef struct VkImageViewUsageCreateInfo {
    VkStructureType sType;
    const void* pNext;
    VkImageUsageFlags usage;
} VkImageViewUsageCreateInfo;

or the equivalent

typedef VkImageViewUsageCreateInfo VkImageViewUsageCreateInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• usage is a bitmask of VkImageUsageFlagBits specifying allowed usages of the image view.

When this structure is chained to VkImageViewCreateInfo the usage field overrides the implicit usage parameter inherited from image creation time and its value is used instead for the purposes of determining the valid usage conditions of VkImageViewCreateInfo.
